Kazuya Aoi is a Limiter who enrolls in a prestigious academy that trains genetically-engineered soldiers. Having made a promise to his Pandora sister who died in battle, Kazuya must overcome his sadness and become the best he can be.

3. Eden: It's an Endless World!
In the panic surrounding a worldwide pandemic which kills 15 percent of the population and cripples many more, a secret organization, the Propater, topples the UN and seizes control of much of the world. A boy and a girl, raised in an abandoned virology research center, immune to the virus, are attacked by the Propater and escape. 20 years later the boy is the most powerful drug lord in South America. He aids his son from behind the scenes as he evades and eventually with the help of mercenaries from Nomad (some of them former Propater operatives) fights the Propater. As the plot develops focus shifts away from the main character and develops many sub-plots dedicated to terrorism, Human-improvement, the struggle of the developing countries and the power battles between the drug cartels and Propater.

1. Gantz
Thought your life was bad? Sometimes, death is worse. There is no salvation, peace, nor god waiting to receive you into their care. But wait, a god? Maybe you are talking about that big black ball stuck in the room with you. Now you are thrown into a game, fighting green aliens and robot monsters for the chance to survive.
When Kei Kurono is killed, he thus finds himself caught in such a game; a test of his skills, morals and will to survive. His life is not his own, his death spat and trampled upon over and over again. What happens if he does not listen? God knows.
A word of warning: Gantz is not for the faint-hearted, but neither is it as simple as it looks. Gore, rape and violence is rampant, as are portrayals of greed, violence, and all the ugliness that one sees in society today.
Gantz has finished publishing and it has 383 Chapters. It is also Known as: GANTZ, Gantz/Osaka
